Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If digital reality applications are processed locally on client devices, then interaction responsiveness is improved, but hardware complexity and cost increase

Engineering Contradiction:

Improveinteraction responsivenessVSAvoidhardware complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the computationally intensive rendering and processing functions from the client device and relocates them to remote cloud servers. The client device retains only the functions necessary for capturing real-world imagery and displaying augmented content, significantly reducing hardware complexity while maintaining local interaction responsiveness.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a cloud-based rendering service as an intermediary between the user and the digital content. This intermediary handles the complex processing tasks remotely, allowing the client device to remain simple while still achieving high-quality, responsive digital reality experiences through networked communication.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If high-performance GPUs are used in head-mounted devices, then rendering quality is improved, but device portability and accessibility deteriorate

Engineering Contradiction:

Improverendering qualityVSAvoiddevice portability

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent removes the requirement for high-performance GPUs from head-mounted devices by extracting the rendering function to cloud servers. This allows lightweight, portable head-mounted displays to deliver high-quality rendering experiences without needing bulky or expensive local hardware.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses cloud-based rendering to generate digital content that is then transmitted to multiple client devices. This copying approach allows the same high-quality rendered content to be delivered to numerous portable devices simultaneously, eliminating the need for each device to have its own high-performance rendering hardware.

Inventive Principle:

Principle #26Copying

3Device complexity

If computationally intensive tasks are offloaded to cloud servers, then hardware demands are reduced, but network latency increases

Engineering Contradiction:

Improvehardware demandsVSAvoidnetwork latency

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The patent applies local quality by keeping latency-sensitive functions (camera capture, display output) local to the client device while offloading only the computationally intensive rendering tasks to the cloud. This hybrid approach minimizes network latency for critical real-time operations while still benefiting from cloud computing power for heavy processing.

Inventive Principle:

Principle #3Local quality

4Adaptability or versatility

If cloud computing is used for digital reality applications, then accessibility and mobility are improved, but real-time interaction capability deteriorates

Engineering Contradiction:

ImproveaccessibilityVSAvoidreal-time interaction capability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the digital reality system into distinct functional components: local real-time functions (capture, display control) and cloud-based functions (rendering, content generation). This segmentation allows each component to operate in its optimal environment, maintaining real-time interaction capability locally while leveraging cloud computing for enhanced accessibility and versatility.

Inventive Principle:

Principle #1Segmentation

AI summary

A system and method for allowing a smooth transition between a public digital reality experience into a private digital reality experience. A cloud server delimitates a public digital zone where interactions with digital reality applications stored in the cloud server and corresponding digital content are viewable to all users in the public digital zone. When users access the public digital zone, the cloud server detects the users and provides digital content from the digital reality to the users via digital reality devices. Upon reaching predetermined levels of interaction, users may access a personal digital reality view, whereby a smooth transition from a public to a personal digital reality experience takes place, prompting a specific portion of computing power from the cloud server to be dedicated to the specific user to enable personal interactions with the digital content. Users may also invite other users to engage in a multi-user private streaming.
